Dear all could you pls help?!
In a flight one time we have reverser unlock light fluctuate
And one time reverser light.synchro and control valve replaced but the problem still exist.
Any body knows the reason?

I would start by ringing out the S836 RH T/R Not Stowed Sensor and S835 LH T/R Not Stowed Sensor.
If those are good check the gaps of the sensors.
